Background and Aim: Vascular imaging during surgical procedures is very important and has many applications.  There are several methods for intraoperative vascular assessment such as intraoperative angiography, Doppler, and fluorescence-based techniques. The latter group and specially the Indocyanine Green (ICG) Video Angiography (VA) is commonly used for vascular surgery and sentinel node...

PURPOSE To analyze indocyanine green (ICG) angiographic findings of chorioretinal folds. METHODS Eight patients (9 eyes) in whom chorioretinal folds had been diagnosed were enrolled in this study. Color photography, fluorescein angiography (FA) and ICG angiography (IA) were performed. RESULTS Indocyanine green angiography demonstrated choroidal venous congestion and a filling delay of the c...

OBJECTIVE The anterolateral thigh flap is a versatile flap that can be used in a free or pedicled fashion. Because of the large amount of potential soft tissue, low donor site morbidity, and long pedicle lengths, many researchers consider it to be the perfect free flap. However, dissection of this and other perforator flaps can become an arduous experience with learning curves to overcome. Near...

Indocyanine green fluorescence (ICG) angiography of the choroid gives better visualization of the choroidal vessels than does fluorescein angiography. We found that the detachment of the pigment epithelium seems bigger on ICG than on fluorescein angiograms, and pigmented lesions are more clearly delineated.

PURPOSE To facilitate the interpretation of the choroidal dye filling sequence, the use of simultaneous indocyanine green (ICG) and fluorescein angiography was evaluated. METHODS A single-wavelength scanning laser ophthalmoscope (SLO) was modified to a two-wavelength system, permitting the simultaneous recording of ICG and fluorescein angiography. This method has been used in 340 cases. About...

OBJECTIVE Amputations of the lower extremity due to irreversible ischemic tissue loss are performed as distally as possible. Therefore, oftentimes wound-healing disorders develop, requiring additional surgical treatment. METHODS The amputations stumps of 10 patients with irreversible ischemic tissue loss due to arteriosclerosis were investigated within 72 hours postoperatively with indocyanin...

We describe herein intraoperative effectiveness of indocyanine green (ICG) video angiography to confirm dural arteriovenous fistulae. A 62-year-old man with a residual symptomatic dural arteriovenous fistula that was previously embolized at another institution is presented. On neurological examination, the motor strength in his both lower extremities was documented as grade 4 and the patella re...

This is a study of 410 Yanomami indians, of both sexes and various ages living in 16 different regions iI, the Brazilian Yanomami reBel " e, submitted to dermatologic and ophthalmologic examinations with the objective of diagnosing the disea:;e onchocerciasis anh its ocular mani'estations. The resvlts show a high level of endemicity of the disease (306 patients-74.63%) and of ocular involvement...
